Time 35m

Yield 8 servings (2 1/2 to 3 cups)

Number Of Ingredients 9

1 tablespoon unsalted butter
1 large yellow onion, diced small
Kosher salt and freshly ground black pepper
1 pint heavy cream
1/2 cup finely grated Gruyere
1/2 cup finely grated Parmesan
1 teaspoon Worcestershire sauce
1/4 teaspoon freshly grated nutmeg
8 "grates" lemon zest (about 1/2 teaspoon)

Steps:

Cook the onion: In a medium saute pan, combine the butter and onions with 2 tablespoons water and a generous pinch of salt over medium-low heat. Cook, stirring occasionally, until tender, 8 to 10 minutes. (There should be little liquid in the pan and the onion should not be browned.)
Make the cream base: In a saucepan, add the cream and warm over medium heat. Allow the cream to come to a boil and reduce slightly, 2 to 3 minutes. Add the Gruyere and Parmesan and let melt a little. Add the Worcestershire, nutmeg, lemon zest and salt and pepper to taste. Whisk the ingredients together in the pan and let it cook until the cream thickens, 2 to 3 minutes.
Pour the cream base over the onions and bring to a simmer. Remove from the heat, then stir and let the mixture rest for 2 to 3 minutes. Taste for seasoning.
